Options to consider in Erdington

Widening an opening

Turning a window into doors, or making an opening wider, means cutting the wall and fitting a new lintel or steel beam sized by a structural engineer. Building control must approve the structural work. We organise the calculations, temporary supports, steel and making good, and show these costs on their own lines in your quote.

Sliding patio doors

Two or more large panels slide past each other on a track, so nothing swings into the room or onto the patio. Sliders give the biggest uninterrupted panes and the narrowest frames, which makes them a good choice where the view matters more than opening the whole wall. Aluminium sliders also suit wide openings.

Before you book in Erdington

How long does fitting take?

Fitting doors into a ready opening usually takes one to two days. If we're widening the opening, allow another two to four days for propping, cutting, fitting the beam, inspection and making good. Manufacture usually takes four to eight weeks after the design is signed off, depending on the material and colour.

Which postcodes in Erdington do you work in?

We cover B24 and the streets around them. If you're on the edge of Erdington, neighbouring Castle Vale and Walmley are covered too.

What should I check before ordering?

Think about the floor level inside and out: a flush threshold needs the patio set lower, with drainage at the door. Decide which side the panels should stack and where the everyday traffic door goes, keeping furniture in mind. If the doors face south or west, ask about solar control glass to keep the room cooler.

Who approves bi-fold and patio doors in Erdington?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Erdington is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
